Consequences of frequent changes to website titles and keywords.
A few moments ago, many websites disappeared from Baidu's rankings and were demoted. I believe they have all experienced this situation. After reviewing, many websites have problems. Mainly following the continuous upgrade of Baidu's algorithm, multiple algorithms perform rating detection on a website at the same time. If there are more elements that do not meet the relevant algorithm, Baidu will downgrade the website.
1. Website domain name resolution error
SEO优化课程 比较关注内容和外链，对根本的操作却忽视了。 When many network promoters do SEO, the SEO optimization course pays more attention to content and external links, but ignores the basic operation. For example, there are many unresolved problems with domain name double resolution. After the spider found that the content of the two sites is completely the same, it is impossible to determine which one is the preferred domain of the website, and it is not easy to rank, and only the website can be downgraded.
2. Website configuration or basic operation is not in place
Baidu retrieves a large number of websites every day. If the server is unstable and the page speed is too slow to load, the overall content quality and page quality are too poor will cause spiders to rate pages and websites. One of Baidu ’s algorithms is user experience. The website itself is not done well, and users will definitely not give high marks when they experience it.
3. Frequently change the title and keywords of the website
The title of the website is equivalent to the name of a person. If the title of the webpage is frequently changed, Baidu will not recognize the website, and the spider will need to spend more time recognizing the website. In this case, the spider will temporarily lower the website Right status.
